ENHANCED INTEGRATION OF POWER INVERTERS USING POLYMER COMPOSITE ENCAPSULATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022179 titled 'ENHANCED INTEGRATION OF POWER INVERTERS USING POLYMER COMPOSITE ENCAPSULATION

Simplified Explanation

The abstract describes a power control system for an electric vehicle that includes a power inverter with a switch module, a controller board, and a gate driver board. The system also includes a first housing made of polymer composite, which encloses the power inverter and defines a cooling cavity in thermal communication with a surface of the switch module. The housing also encapsulates a portion of at least one of the switch module, the controller board, and the gate driver board.

• The power control system is designed for use in electric vehicles.
• It includes a power inverter with a switch module, a controller board, and a gate driver board.
• The switch module comprises multiple power switches.
• The gate driver board is in communication with the controller board and is responsible for driving the gates of the power switches.
• The first housing, made of polymer composite, encloses the power inverter and provides thermal communication with the switch module.
• The housing also encapsulates a portion of the switch module, the controller board, and the gate driver board.

Potential applications of this technology:

• Electric vehicles: The power control system can be used in electric vehicles to efficiently control the power flow and ensure optimal performance.

Problems solved by this technology:

• Heat dissipation: The first housing, with its cooling cavity, helps dissipate heat generated by the power inverter and switch module, preventing overheating and ensuring reliable operation.

Benefits of this technology:

• Improved efficiency: The power control system, with its power inverter and switch module, allows for efficient control of power flow in electric vehicles, resulting in improved overall efficiency.
• Enhanced reliability: The encapsulation of the switch module, controller board, and gate driver board within the housing helps protect them from external elements, increasing the reliability and lifespan of the power control system.
